CORN-HARVESTER.

4 sPECIFICATIoN forming part of Letters Patent No. 541,562, dated June 25,1895.

' Application flied umher 1, i392. seen No. 447,543; cr mpaei.) i

Be it known that I, JAMES E. MAZELIN, acitizen of the United States,'residing at Baltimore, inthe county of Fairfield, State of Ohio, have invented certain new and useful Improvements in Corn-Harvesters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention lrelates to corn harvesters, and has for its object to improve the general construction of this class of machines whereby their efciency and usefulness are iucreased in an eminent degree.

The improvement consists of the novel features andthe peculiar construction and combination of the .parts which will be hereinafter more fully described and claimed and which are shown in the annexed drawings',` in

which- Y Figure 1 is atop plan viewof a machine embodying my invention. Fig. 2 is a View from the rear side, showing the shocker tipped into a vertical position. Fig. 3 is a front View. Fig. 4 is a longitudinal section of the shocker, showing the means for holding the Fig. 5 isa de-` band in an adjustable position. tail Viewr showing the means for raising and lowering the drive-Wheel. View showing the means for raising andlowering the grain-wheel. Fig. 7 is a detail view of the elevating-chain.

for limiting the movement of the shocker.

The machine is supported and nicely bal-1 anced upon the drive wheel B and the grain,

wheel O, both of which wheels are relatively adjustable in a vertical direction to changel E are located on .the opposite side of the inachine and have the drive wheel B located below the upper end of the elevator. Traveling 4belts F are provided on the platform A to convey the corn to the elevator D and are supported on sprocket wheels f which are secured on the shattsf which are arranged at Fig. 6 is a detail Fig. S is a detail Viewy showing a portion of the main frame with, the track attached thereto and also thestop the opposite edges of said platform A. The shafts'f are projected, at their front ends and are provided with beveled pinious f2 which mesh with corresponding beveled pinions g on the reel shaftsG which are arranged at the front ends'of the lplatform A, and which are provided at their upper ends with the reel arms g' which are pivotally connected at their inner ends to a hub castingg2 secured to the upper ends of said reel shafts G; The reel -arm's g are adapted to be moved into a vertical position and are supported iu a horizontal position by a disk or collar g3 which is se-` construction is located at the front end of the platform A,and the cutter bar h is reciprocated by means of the lever h whichfis pivotally supported between its ends beneath the platform A'and has its front end in engagement withsaid cutter bar h and its rear end connected with a crank pin on the sprocket 'wheel h2 by means of the pitman h3, said sprocket wheel h2 being on the rear end of a shaft I which is arranged between the upper and lower chains of the elevator and. is driven from the drive wheelnB by the mechanism hereinaftermore fully set forth. Three guards Vproject.forwardgfrom the front end of the -platiorrn A and-dare in opposite directions on their opposing sides to receive the corn and guide the same to the cutting apparatus. The guardsJ .l2 are located in advance of the shaftsf and serve in a measure to shield the ,gearing f2 g and prevent the corn from com- .ing in contact therewith.

The guard .If is located midway between the guards J J? and has'its forward end tapering, as shown, to form the flaring mouth or throat between'the opposing sides of the three guards as hereinbefore stated. The housings j are provided to further protect the gearing f2 g from the corn and other matter which would have a tendency to lodge in said gearing and choke the same.

The elevator D is of ordinary construction andinclines upward from the plane of the platform A and is provided with carrier chains d which pass around sprocket wheels d on the rollers or shafts d2 which are located at opposite ends of the elevator. The upper shaft d2 is projected at one end and provided with a sprocket pinion d3. The inner shaft j is projected on the end correspending with the projected end of the shafts d2 and is provided on said projected end with a sprocket pinion f3. A sprocket chain a passes around the sprocket pinionsf3 d3 and the sprocket wheel h2 and transmits motion from the latter to the shafts f', d2 and the respective carrier chains which pass around said shafts and are operated thereby.

The shocker E is located just below the upper or delivery end ot' the elevator D and is semi-circular in cross section and tapers slightly in the direction of its length, being wider at the end correspondingY with the front portion of-the machine. This shocker is pivotally supported about midway of its ends and is adapted to tilt to a vertical position to drop the shock in a standing position upon the ground. The bearing e for the outer journal of the shocker is adapted to swing horizontally for the purpose of swinging the shocker E free of the shock after the saine has been dropped on the ground thereby enabling the machine to be drawn forward without interfering with the shock.

The journal e on the inner side of the shocker E is provided with a roller (Z4 which is adapted to travel upon atrack e2 when the shocker is swinging laterally. A stop calimits the inward movement of the journal e when the same reaches a normal position when swinging the shocker E back to its first position for receiving the corn. A slight depression 64 is made in the track at its inner end for the roller on the journal e to drop into when the shocker is in a normal position. The track e2, serves to guide the roller d4, and journal e', away from the side member of the frame, and the bearing e, is mounted suiiiciently strong to supportI the shocker when the same is moved outward to carry the bearing e, oft the track. In returning the shocker to its normal position, the track again Serves to guide the roller and its bearing back to the stop es, and depression e4. The hand lever F which is located within convenient reach ot' the drivers seat is connected with an arm e5 of the bearing e by means of the rod f4, bell crank f5, rod f6, bell crank]c7 and the rod f8. The latch K for engaging with a portion of the shocker and supporting it in a vertical position is pivoted to said arm e5 of the bearing e and is operated by means of the foot lever K with which it is connected by means ot the rod 7a, bell crank 7e', rod k2, bell crank k3 and the rod 704, and is returned to a normal condition after being actuated by means of the springs 755. The latch L for engaging with the forward end of the shocker E for supporting the same in a horizontal position is connected with the hand lever L' which is located within convenient reach of the drivers seat by means of rod l, bell crank Z', and the rod Z2 and is held in an operative position by means of the springs Z3.

The band holding mechanism which is ad justably connected with the shocker so as to change the position of the band to adapt the same for varying lengths of corn, is located on the under side of and is supported by said shocker and comprises a head M- which is adapted to slide in suitable guides provided on the shocker, and which is provided with a tlxed bill m and a rotatable bill m,the shank ot' the latter extending through the head M and provided with a lever m2 by means of A which said bill m is turned in said head M. A pivoted latch m8 is provided to engage with the lever m2 and retain the bill m in proper position to retain the hand m4 in place between the bill lm, and in. A spring m5 holds the latch mi in proper position with the lever m2 and retains the same in position to hold the band m4 in place. A slotted bar M projects froin the head M and is held in the required position by binding screws or other suitable fastening m6 which passes through the slot in said bar and enters a portion of the shocker frame E. On loosening the bindings crew m6 the'head M and the appliances carried thereby can be removed to change the relative position ofthe band hold ing mechanism relative to the shocker for the purpose aforesaid.

The holderNfor retaining the shock in place in the shocker E after the latter has been tilted to'a vertical position is pivotally supported on a vertical standard N and is composed of an arm n and a fork n the 1atter being adjustably connected with said arm n by means of a binding screw n which passes through the slot in the shank of the fork and screws into the said arm n. The outer ends of the fork are provided with stops nl which engage with the shocker and limit the movement of the same when tilted into a vertical position. Prongs n2 project beyond the top edges of the shocker E and are adapted to have the ends of the band m4 attached thereto. These prongs are so disposed that when the shocker is tilted into a vertical position they will overlap the ends of the fork n whereby the fork and shocker will mutuallyV strengthen and brace each other. By reason of the fork n being adjustably connected to the arm n, said fork can be regulated to suit the size of the shock. The lever L is connected with an arm pro jected from holder N by means of the rod n3, bell crank n4 and the rod a5. It will be seen that the latch L and the shock holder N are both connected with the same hand lever L'. Hence on operating the latter the latch L is released and the holder N is brought into loo' position to come opposite the shocker E when the same is tilted into a vertical position.

A holder for retaining the corn during the time the shocker is operated for discharging the shock and returning into an operative position to receive the corn for forming another shock, is composed of a shaftO which extends parallel with the shockerwhen the latter is in a horizontal position, and curved arms o which project laterally from said shaft O. A crank 0 on the front end of the shaft O is connected With the foot lever O by means of the rod o2, bell crank o3 and the rod o4. During the interval thatthe corn isrbeing received in the shocker, the curved arms o will occupy a pendent position, but after the shook is formed and while the same is being bound and discharged, the operator will press on the foot lever O to throw said. curved arms o into a horizontal positionA so as to receive the corn. After the shock has been discharged and the shocker has returned to a normal position, the foot lever O is actuated to operate the shaft O so as to discharge the corn received by the arms o into the shocker E.

` The reel bordering upon the elevator D is provided with a spiral cam guide rail P to engage with the pivoted reel arm and elevate the same as they approach the elevator D, therebygiving clearance for the grain or corn as it travels up the elevator D. This guide rail P serves to lift the outer end of the reel arm as the same passes by the elevator D to prevent interference of said arms with the efficient Working of said elevator.

The shaft I is provided with a bevel pinion t' which is adapted to mesh with al corresponding beveled pinion t on the end of a counter shaft Q. A sprocket pinion q mounted on the shaft Q so as to turn loosely-thereon is provided on one face With a half clutch which is adapted to engage with a corresponding half clutch g which is keyed to revolve with the shaftQ but is free to slide thereon, being held in engagement with a half clutch on the sprocket pinion q by means of the spring q2. A shipper g3 is provided to engage with the half clutch g and move the same in and out of engagement with the half clutch on the sprocket pinion q as required. A lever g4 is provided to operate said shipper g3. A sprocket wheel Q mounted so as to revolve with the drive Wheel B imparts motion to the sprocket chain Q5 which passes around said sprocket Wheel Qand sprocket pinion q.

The journals of the drive wheel B are mounted in bearings S which are located in curved slotsfs formed in castings S which are secured to the frame of the machine. The opposing sides of the slotss have vertical grooves to receive the vchain or cable s by means of which the position of bearings S is changed with reference to castings S. One end of the chain or cable s is secured to the lower corner of the casting S and extends vertically and passes over a pulley s2 at the upperend of the bearing S, thence down and around a pulley s3 at the opposite corner of said casting S 4and extends to the rear end of the machine where its opposite end is attached to a windlass S2 which is operated by an ordinary lever and ratchet mechanism S3.

The grain wheel C is carried by the rack bar T which is mounted in a vertical guide. A

short shaft T having pinion t is provided to engage with the rack bar T to move said rack bar vertically to change the relation of the platform A and thegrain wheel C. A ratchet wheel t and a pawl t2 are provided to retain the grain wheel C in the adj usted position.

The carrier chains are composed of links U and the couplings V, the latter having hooks of at its opposite ends to receive the ends of the cross bars of the links U. The fingers or prongs fu. for engaging with the corn for carryingthe same along in a positive manner are let in the couplings and have their base portions extended to close the hooked ends of said couplings and retain the links U in position.

The operation of the machine, is obvious from the foregoing detailed description and it is not deemed necessary toV enter into a lengthy further description of the same.

By having the band holding mechanism located in the lower portion of the shocker, the position of the said band is fixed and maintained beyond any peradventure of slipping. Moreover, when the ends of the bands are grasped to bind the shock and are brought over the same, the said bands will be positively held at diametrically opposite points and can easily be secured in the predetermined posif tion.Y f

Having thus described my invention, wha I claim, and desire to secure by Letters Patent, isf l.
